12.1 Telephone Number Formats in Outlook
To be able to effectively use Outlook together with SwyxIt!, the external numbers in Outlook Contacts must be saved –as recommended by Microsoft– in the so-called “canonical telephone number format”. A canonical number always begins with a plus sign. This is followed by the country code (e. g. ‘44’ for Great Britain), the local area code without the preceding zero in parentheses, and then the number.
Example of a number in London, Great Britain:
+44 (20) 12345678
You can add spaces to improve the clarity of the number, however, it is not necessary. Extension numbers, in the case of private branch exchanges, can also be separated from the subscriber number by a hyphen.
Example:
+44 (20) 12345-67
Pay attention to the country-specific particularities, as in Italy, for example: The preceding zero must be included here in the local area code.
